openly, for there was nothing left to see with" [MooglyGuy]
* Enabled vector bloom and associated .ini controls
* Added raster bloom and associated .ini controls, each bloom "level" is the
linear weight of successively half-sized render targets
* Removed D3D8 mode
* Mass renaming in D3D renderer to use namespaces, initial planning step to
HAL-based renderer implementation on Windows (i.e., GL on Windows)
* Converted d3d_info, d3d_poly_info, and d3d_texture_info into classes
* Added batching of vectors for possible speed increase
* Minor cleanup of shader state setting
